NONMEM 7.4.1
Colleagues
I am trying to use the ACCEPT option in $DATA in order to select a subset of
records (to evaluate the impact of the # of samples/subject on confidence
intervals).
I used the following code:
ACCEPT=(TIME=0, TIME=1, TIME=2, TIME=4, TIME=6, TIME=24)
NMTRAN then
from the manual:
"When the IGNORE option is used to filter records from the input file,
the .EQ., =, .NE., and /= symbols perform literal string comparisons. To
provide a numerical equality comparison, use .EQN. for numerical equals,
and .NEN. for numerical not equals."
May be there is a
Hi Dennis,
I don’t have an elegant solution for you (and I’ve been pining for the use
of combined Boolean operations like “TIME.GT.5.9.AND.TIME.LT.6.1” for a
long time).
An inelegant solution could be to run the model once with a write statement
to see if you can identify the value like
Similar to Bill, I also have an inelegant, but workable, solution, which is
to brute force the ignore times by templating them in R.
For example, you can use a simple glue template to churn out ignore
statements. For simplicity this could then be then just copied into control
streams.
Hi Dennis,
Unfortunately, my reply will not provide a solution to your problem. It is more
about drawing attention to the fact that checking conditions numerically is not
exactly the same as checking conditions on a piece of a paper, because of
rounding. I’m sure that the users of the List are

I would accept that if the problem related to decimals. Your code does not
apply to integers (please provide an example if that is the case) - so it would
only apply if NMTRAN does something weird to integers.

My apologies — my question reflected a (complicated) error on my part. NMTRAN
/ NONMEM were doing the correct thing.
Of note, Leonid proposed using .EQN — that does not appear to be necessary.
